 So I had to look this one up. It says Tua Day, T-A-U Day. And I was like, well, what does that even mean? And apparently it is the anti-Pi Day in the world of math. T-A-U or T-U-A? T-A-U. Okay, so Tau. Oh, it's Tau. Tau Day. Tau Day, which is the opposite of Pi Day. Pi. Interesting. Yeah, there's a lot of weird Eastern philosophies that kind of center around the concept of Tau.
